I'm keen on a REV A. Again, it is a budget issue. Posted this on the Cinema5D but it seems no one has responded to have this camera/laptop combo. I have a Octo mac pro, so no editing will be done on the MBA. I just want it to play the raw H.264 movies on the MBA. I've read that the rev B has H.264 acceleration, I can't seem to find it on the Rev A. For your reference here are some sample videos Video Page - to get the file use SAVE LINK AS Direct 1 Direct 2 Direct 3 To summarize: 1) Will it play smoothly with the base rev A? Otherwise, what specs did you have rev B, hdd, ssd, processor? 2) base unibody Macbook is in the same price range and there is H.264 accel and I'm considering it too although I prefer the form factor of the MBA. TIA!
